drm: rcar-du: Add support for the R8A7794 DU
drm: rcar-du: Add support for the R8A7793 DU
This pull request introduces the vc4 driver, for kernel modesetting on
the Raspberry Pi (bcm2835/bcm2836 architectures). It currently
supports a display plane and cursor on the HDMI output. The driver
doesn't do 3D, power management, or overlay planes yet.

The R8A7794 DU has a fixed output routing configuration with one RGB
output per CRTC and thus lacks the RGB output routing register field.

This is enough for fbcon and bringing up X using
xf86-video-modesetting. It doesn't support the 3D accelerator or
power management yet.
v2: Drop FB_HELPER select thanks to Archit's patches. Do manual init
ordering instead of using the .load hook. Structure registration
more like tegra's, but still using the typical "component" code.
Drop no-op hooks for atomic_begin and mode_fixup() now that
they're optional. Drop sentinel in Makefile. Fix minor style
nits I noticed on another reread.
v3: Use the new bcm2835 clk driver to manage pixel/HSM clocks instead
of having a fixed video mode. Use exynos-style component driver
matching instead of devicetree nodes to list the component driver
instances. Rename compatibility strings to say bcm2835, and
distinguish pv0/1/2. Clean up some h/vsync code, and add in
interlaced mode setup. Fix up probe/bind error paths. Use
bitops.h macros for vc4_regs.h
v4: Include i2c.h, allow building under COMPILE_TEST, drop msleep now
that other bugs have been fixed, add timeouts to cpu_relax()
loops, rename hpd-gpio to hpd-gpios.

The plane reset handler frees the plane state and allocates a new
default state, but when doing so attempt to free the plane state using
the base plane state pointer instead of casting it to the
driver-specific state object that has been allocated. Fix it by using
the rcar_du_plane_atomic_destroy_state() function to destroy the plane

Compared to wrapping the final kref_put with dev->struct_mutex this
allows us to only acquire the offset manager look both in the final
cleanup and in the lookup. Which has the upside that no locks leak out
of the core abstractions. But it means that we need to hold a
temporary reference to the object while checking mmap constraints, to
make sure the object doesn't disappear. Extended the critical region
would have worked too, but would result in more leaky locking.
Also, this is the final bit which required dev->struct_mutex in gem
core, now modern drivers can be completely struct_mutex free!
This needs a new drm_vma_offset_exact_lookup_locked and makes both
drm_vma_offset_exact_lookup and drm_vma_offset_lookup unused.
v2: Don't leak object references in failure paths (David).
v3: Add a comment from Chris explaining how the ordering works, with
the slight adjustment that I dropped any mention of struct_mutex since
with this patch it's now immaterial ot core gem.

This was accidentally disabled by commit 4b096ac10d ("drm: revamp

...
* removes the now unused DRM slave encoder support, which all users have
migrated away from, allowing us to simplify the code.
* ensure all pending interrupts are processed together, rather than
needing the handler to be re-entered each time.
* use more HDMI helpers to setup the info frames.
* fix EDID read handling by ensuring that we always wait the specified time
before attempting to read the EDID, no matter where the EDID read request
came from.
